Air Address vs DNSSEC

Air Address is a small utility that lets you show all information about your current internet connection. The Air Address app tells your current external public IP address and provides additional network and address information as well. INTERNET ACCESS DETECTION • Check the Internet access state. • Detect the active network interface type (Wi-Fi, Cellular, Bluetooth, VPN) used for Internet access. EXTERNAL ADDRESS INFORMATION • Very detailed information about your public external IP address. • Detect DNS hostname, address space type (RIR), internet service provider (ISP), autonomous system (AS) and geo-location. • Detect PING response capability. • Show WHOIS record. DNS SERVER INFORMATION • List the active DNS servers. Show hostname, network type, MAC address (on Wi-Fi network only), PING capability, WHOIS record. • Show search domains (mDNS/Bonjour related network domain names). DEFAULT GATEWAYS • List the default gateway (router) addresses of active network interfaces. • Show hostname, network type, MAC address (on Wi-Fi network only), PING capability, WHOIS record for each default gateway. • Full offline MAC vendor database.

DNSSEC routes your device's DNS queries through a DNSSEC-validating resolver — in one tap, without a VPN. Modern DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) encrypt your queries in transit. DNSSEC validation at the resolver ensures the answers haven't been tampered with. Together they make DNS the private, trustworthy channel it was always meant to be. BUILT-IN DNS4EU PRESETS DNS4EU is the European Commission-backed public resolver network. Four presets ship with the app: • Protective — blocks malware and phishing domains • Protective + Ad Blocking — adds tracker and ad filtering on top • Protective + Child Protection — adds adult content filtering • Unfiltered — encrypted and DNSSEC-validating, no content filtering Pick a preset and tap Apply. iOS will prompt you once to allow the DNS profile, then it's active system-wide. YOUR OWN RESOLVER Prefer a different provider? Add any DoH or DoT endpoint: • Enter a DoH URL (https://…) or a DoT hostname • Optionally add fallback IP addresses for bootstrapping • Flag it as DNSSEC-validating to track which resolvers you trust Custom resolvers are stored on-device and never leave it. ONE TAP, SYSTEM-WIDE The profile installs via the operating system's built-in DNS Settings — no VPN tunnel, no proxy, no configuration profile to trust manually. Once applied, every app on your device uses the configured resolver. Remove it any time from within the app or from Settings › General › VPN & Device Management › DNS. WORKS EVERYWHERE Available for iPhone, iPad, Mac, Apple TV, and Apple Vision Pro.
